Air filters

The differences in air purifiers

Large differences in air cleaner, based on the types of irritants, which cleans, as efficient as they are quieter and much more. There are two basic types of pollutants, air purifiers are designed to clean: the emission of gaseous and particulate emissions.

Particulate pollutants can cause problems if you have less than 10 microns in diameter, in particular, as they can beeasily inhaled into the lungs. The smallest of these tend to both lungs, where they remain for years or blocked blood flow. The EPA has long recognized that fine particles of pollution and forest fires are a serious health problem, the circulatory and respiratory problems more difficult and can cause premature death. Numerous studies have reduced pollution by particulate matter increased hospital admissions, reduced lung function and life expectancy, cancer associatedSchool and absenteeism increased. Most affected are children, elderly, people with asthma and other respiratory diseases, and patients with cardiovascular disease.

Gaseous pollutants are things like the gas stove with no ventilation and heating, smoke, automobile exhaust gases by means of furniture and building materials like particle board and plywood, personal hygiene, cleaning products, paints and varnishes. Although outgas paints and varnishes, as a rule veryFast, chemicals from furniture such as sofas and mattresses, particle board and carpet can outgas for years. If you have a problem with the gaseous pollutants, such as chemical sensitivity, asthma, or a new house or renewed do not need an air filter, a good job of reducing gas. If there are additional costs that an air purifier filter gaseous pollutants and chemicals probably do well for us if weperfect "green" home, and we are all exposed to chemicals for many.

Small Air Filter

Very small air purifiers are not only effective in removing pollen and dust. Moreover, not made to clean the fine particles or gaseous materials.

Electronic and ionic air filters and ozone generators

According to the EPA remedy, the use of electronic air purifiers and ion generators, an electric charge in the airParticles. These devices may produce ozone, an irritant to the lungs. The EPA has expressly said that the ozone generators are ineffective and a danger to health.

HEPA filter (mechanical) air

Uses high-efficiency particulate air (HEPA) in the cleanroom industry and doctors, and increasingly in residential air purifier used because they are highly effective in removing particles such as pollen andParticles of smoke and forest fires. These filters are "true" HEPA if at least 99.97% of all particles larger than 3.0 microns removed. If the filter you see is kind of like "HEPA" can not be true HEPA. Always ask if you are unsure.

Some air filters to remove gaseous pollutants, particulate matter, if you do not have the special equipment and other HEPA filters. Often this is achieved with activated carbon.

InFinally, it is important to decide whether you want an air purifier that eliminates a significant amount of polluting gases and particles of need. The best type of particle removal problem is a true HEPA filter. IQAir and Austin are both true HEPA filters and air cleaners offer the gas and particles removed.
